Installig klik

I am a newbie to Linux, I'm using Mepis 6.5, and I want to install klik-the commands given are as follows:
wget klik.atekon.de/client/install -0 [sh
What is the symbol before sh, I am using the key to the right of the p in lower case,the symbol looks like a vertical line in the install instructions, but my keyboard doesn't have that key so I thought it might be the one I'm using. Any help would be greatfully received. Thanks van
